Abstract :
In order to investigate the effect of manuring fertilizer and super absorbent under water deficit conditions on the morphological٫ quantitative and qualitative characteristics of soybean under water deficit stress condition an experiment were conducted with three replications in form of split factorial based on complete block design at field of Islamic Azad university, Varamin branch.Treatment were include water deficit stress (normal irrigation, limited irrigation after poding), manure fertilize (control, 15 tha-1and 30 tha-1) and super absorbent (control, use of super absorbent 15 kgha-1). irrigation treatment Was considered as main plot and manure fertilizer and super absorbent were placed factorialy at sub plot, The results showed that the simple effect of irrigation had significant effects on the branch number, first pod distance٫ pod number in branch, pod number in stem, pod number in plant, protein percent, protein yield,oil yield٫ biologic yield and Seed yield. The simple effect of manure Was significant on branch number, first pod distance, seed number in pod, pod number in stem, pod number in plant, oil percent, oil yield, protein percent, protein yield, seed number in plant, biologic yield and Seed yield. The simple effect of super absorbent Was also significant on first pod distance, pod number in branch, pod number in stem, pod number in plant, protein percent, protein yield, seed number in plant, biologic yield , Seed yield and harvest index. The triple interaction had a significant effect on pod number in stem, pod number in branch, pod number in plant, oil yield, protein percent, protein yield, seed number in plant , biologic yield and Seed yield. Water deficit decreased all plant characteristics compared to the normal irrigation, but application of super absorbent and manure fertilizer in water stress condition increased all morphological, quantitative and qualitative characteristics of soybean.
